概要

• 論文の詳細を見る

• TiCo, a d-band metal, is known to be an exchange-enhanced itinerant paramagnet. We measured the dc susceptibility of polycrystalline Ti_<0.5+χ>Co_<0.5-χ> with small χ over the temperature range of 1.7 to 300K. In order to study superconductivity, the ac susceptibility of this compound was also measured down to 14mK. We observed superconductivity in this system, whose superconducting transition temperature was approximately 35mK for Ti_<0.510>Co_<0.490>.
